The kanamycin concentration 30 mg/L was determined to be the most suitable for selecting transgenic plants. 297 transgenic plants resistant to kanamycin were obtained,of which 9 positive transgenic plants were verified by PCR detection,and the transgenic rate was 0.37%. RT-PCR detection showed that the expression level of BraVPE in transgenic plants decreased significantly,reliability of transgenic plants was verified. Therefore ,the above results laid a foundation for further study in BraVPE gene functions. %K 真空渗入法 大白菜 BraVPE转基因 RNAi载体< %K br> %K Vacuum infiltration Chinese cabbage BraVPE Genetic transformation RNAi vector %U http://xbnyxb.alljournals.cn/ch/reader/view_abstract.aspx?file_no=20170213&flag=1
